There were some instances during the guncam footage of tracer rounds hitting paved roads and shooting nearly straight up. But only one or two out of every 3 or so second burst.
Btw there is one slight problems with the Tiger and whether or not the engine compartment was armored ... most were completed by 44, as were most of the main battle tanks. (Panther is an exception, it started production in '43 and continued to the end of the war)
A total of 1,354 Tigers were built between Aug 1942 and Aug 1944 when production ceased.
The German industry, in the case of it's heavy tanks, did not keep producing tanks up until the end of the war. During late 1942, most of '43 and early '44, nearly all the tanks that would serve during the remainer of the European conflict were produced, before the industrial sectors had to scamp on raw materials. The only real problems with the heavier German tanks were replacement parts such as engines, bearings and other parts made to wear out, as these had to be constantly replaces.
Even the rehashed chassis from earlier conflicts still had their armor intact, which had been produced during what could still be called the offensive (but in actuallity a stale mate) period in Russia.
Only the Pz IV and the Pz V Panthers were really subject to manufacturing problems during mid '44 to the end of the war, as they were in continued production.
